CVE-2026-77768: Authorization Bypass Through User-Controlled Key in Openpanel-dev openpanel
Description
CVE-2026-77768 is an authorization bypass vulnerability in the Openpanel-dev openpanel product. The vulnerability exists in the report.get procedure, which accepts only a reportId and returns the report data without proper project or organization membership checks. This allows any authenticated user to access the full configuration of any saved report by supplying its identifier. Other related procedures such as update, delete, and duplicate correctly enforce project access checks, so the issue is isolated to the report.get procedure.

Technical Analysis
The report.get procedure in openpanel accepts only a reportId and returns the report data directly via getReportById(reportId). The enforceAccess middleware only evaluates membership when the input includes projectId or organizationId keys, which report.get does not provide. Consequently, an authenticated user can bypass authorization and retrieve any report's full configuration, including sensitive details like owning projectId, event series, filters, breakdowns, and formulas. Adjacent procedures perform proper project access validation, indicating the flaw is specific to report.get.
Potential Impact
Any authenticated user can read the full configuration of any saved report on the openpanel instance without proper authorization. This exposure includes sensitive project-related data and report configurations. The vulnerability does not allow modification or deletion, only unauthorized read access. The CVSS score of 6.5 reflects a medium severity impact with high confidentiality impact but no integrity or availability impact.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user access to trusted users only and monitor for unusual report access patterns. Consider implementing additional access controls or input validation to ensure project or organization membership is enforced on report.get requests.
